The public service broadcaster was found to have committed a "major breach" of broadcasting rules by not revealing that the presenter of a documentary about the Gaza situation was the offspring of a Hamas representative, as determined by UK media regulator Ofcom.
An inquiry by the broadcasting watchdog into the programme Gaza: How to Survive a Warzone has determined that the programme was "significantly deceptive".
The BBC's director general had previously apologised, saying there had been "a significant failing in relation to accuracy".
Ofcom has directed the corporation to broadcast a evening declaration about its conclusions.
"Given this constitutes a serious breach of our regulations, we are instructing the BBC to transmit a message of our conclusions against it on BBC2 at 9pm, with a schedule to be finalised," the statement read.
'Possibility to Damage Confidence'
The regulator's report said: "Our investigation determined that the programme's omission to reveal that the presenter's parent occupied a position in the Hamas-run authority was substantially inaccurate.
"Consequently that the audience did not have vital facts which may have been extremely pertinent to their judgment of the presenter and the information he shared.
"Trust is at the center of the connection between a television network and its public, particularly for a national broadcasting corporation such as the public broadcaster.
"This failing had the risk to damage the significantly high amounts of credibility that the public would have put in a documentary produced by the BBC about the conflict in Gaza."
The film was pulled from the online platform in last February after the boy's family links were revealed, and in July an internal BBC review found it breached the organization's content policies on truthfulness.
A corporation official stated: "The Ofcom ruling is in line with the results of the corporation's inquiry, that there was a serious error in the programme in relation to the broadcaster's journalistic policies on truthfulness, which reflects clause 2.2 of the regulator's media standards.
"We issued an apology for this and we accept Ofcom's decision in its entirety. We will follow the directive as soon as the timing and wording are finalised."
